“…It is noted that the shape of μ 0 H c2 ( T ) curve does not change qualitatively when μ 0 H c2 ( T ) is defined by different criteria in this compound. In addition, a slight upward behavior near T c which commonly observed in some IBSs143334, is also observed for both directions, might be due to the flux dynamics as is seen in cuprates35.…”

The temperature dependence of upper critical field μ0Hc2 of Ca0.83La0.17FeAs2 and Ca0.8La0.2Fe0.98Co0.02As2 single crystals are investigated by measuring the resistivity for the inter-plane (H//c) and in-plane (H//ab) directions in magnetic fields up to 60 T. It is found that μ0Hc2(T) of both crystals for H//c presents a sublinear temperature dependence with decreasing temperature, whereas the curve of μ0Hc2(T) for H//ab has a convex curvature and gradually tends to saturate at low temperatures. μ0Hc2(T) in both crystals deviates from the conventional Werthamer-Helfand-Hohenberg (WHH) theoretical model without considering spin paramagnetic effect for H//c and H//ab directions. Detailed analyses show that the behavior of μ0Hc2(T) in 112-type Iron-based superconductors (IBSs) is similar to that of most IBSs. Two-band model is required to fully reproduce the behavior of μ0Hc2(T) for H//c, while the effect of spin paramagnetic effect is responsible for the behavior of μ0Hc2(T) for H//ab.

The crystallographic and magnetic properties of the Mn͓N(CN) 2 ͔ 2 compound have been investigated by dc magnetization, ac susceptibility, specific heat, and zero-field neutron diffraction on polycrystalline samples. The magnetic structure consists of two sublattices which are antiferromagnetically coupled and spontaneously canted. The spin orientation is mainly along the a axis with a small uncompensated moment along the b axis. The ground state is a crystal-field sextet with large magnetic anisotropy. The crystal structure consists of discrete octahedra which are axially elongated and successively tilted in the ab plane. Comparisons of the magnetic structures for the isostructural M ͓N͑CN͒ 2 ͔ 2 (M ϭMn, Fe, Co, Ni͒ series suggest that the spin direction is stabilized by crystal fields and the spin canting is induced by the successive tilting of the octahedra. We propose that the superexchange interaction is the mechanism responsible for the magnetic ordering in these compounds and we find that a crossover from noncollinear antiferromagnetism to collinear ferromagnetism occurs for a superexchange angle of ␣ c ϭ142.0(5)°.

“…The magnetic structure includes two magnetic subsystems (copper and rare earth). The Cu spins become antiferromagnetically ordered at TN(CU) = 285 K and the intrinsic ordering of the rare earth magnetic subsystem occurs at TN(Sm) = 5.9 K. The spin arrangement in each magnetic subsystem is known from neutron experiments [19,20]. The antiferromagnetic ordering of the copper spins in Sm2CuO4 again preserves the space inversion symmetry of the system.…”

“…Unlike GdzCuO4, Sm2CuO4 does become superconducting under doping. In this case it is the possible influence of the magnetic ordering of the rare earth subsystems onto the superconducting state which has attracted attention to the magnetic subsystem of this compound and an investigation of the upper critical field He2 of Sml.ssCeo.lsCuO4 gives indications for such an influence [18,19]. In Sm2CuO~ we have also disappears reaching a critical field while a residual electric polarization remains.…”

Experimental studies of the magnetoelectric effect in the antiferromagnetic crystals Cr20 3, Gd2CuO4 and Sm2CuO 4 have been performed in strong magnetic fields up to 20 T. The magnetoelectric effect is fully determined by the symmetry of the magnetically ordered material and yields hence valuable information about magnetic ground states. When the magnetic symmetry is changed at a magnetic field induced phase transition the magnetoelectric effect exhibits anomalies at the phase transition owing to the fact that the magnetoelectric signal is related to the antiferromagnetic order parameter L. Even at temperatures close to the Nrel temperature TN the obtained experimental data resolve the magnetic properties very well, giving the possibility to study magnetic phase transitions in the critical temperature range.
